Title: Method and circuit for generating address mark
Inventor: HASE KENICHI
IPC: G11B20/14
Filed: 1988-03-26
Abstract: PURPOSE:To decrease unnecessary patterns with a small circuit scale and to output an address mark detecting signal in an early stage by detecting the 8B pattern of an NRZ (Non-Return to Zero) signal and generating a 2-7 illegal pattern. CONSTITUTION:The title circuit is composed of an encode shift register 1 to temporarily store an NRZ input signal, an encoder 2 to convert the NRZ signal into a 2-7 code, an '8B' pattern detecting circuit 3 to detect the '8B' pattern from the contents of the encoder shift register 1, and a 2-7 illegal pattern generating control circuit 4 to generate a control signal. Further, the circuit uses a data sequence itself in order to generate the 2-7 illegal pattern, and the circuit selects '8B', which is 1-byte data of the NRZ signal having the small number of data bits as the data sequence and suitable for deformation into the 2-7 illegal pattern. Thus, the unnecessary patterns can be decreased, and the address mark detecting signal can be promptly outputted.

Abstract: PURPOSE:To improve the active material holding capacity of a pole plate by making the pole plate filled with paste to pass between the rollers having fine projections and through a drying furnace followed by making it pass between the rollers having the smooth surfaces with no projections. CONSTITUTION:A lead grid 2 traveling on a belt conveyer 1 is filled with paste by a paste filling machine 3 to make it into a pole plate 4. Said pole plate is made to pass between a pair of rollers 5 and 5' having fine projections on their surfaces while being dried properly by a horizontal type drying furnace 6. Then, said pole plate is passed between a pair of the rollers 7 and 7', whose surfaces are smoothed by coating the iron rolls with the sheets 8 and 8' made of Teflon resin, for being transferred to the next aging process. Accordingly, the hanging down of an active material is corrected by the rollers 7 and 7', while the pole plate surface in a semi-dried state is smoothed thus being able to prevent the active material from falling down and to suppress the generation of dust during the process.

Title: Apparatus for management and maintenance of electroless plating bath
Inventor: CHIBA SHIGEO
IPC: C23C18/52
Filed: 1982-04-30
Abstract: PURPOSE:To avoid disadvantage due to the time lag of analytic data, by a method wherein an ultrafiltration apparatus is interposed in the plating bath passage connecting a plating bath tank and a component analytic apparatus and a filtrate is returned to the plating bath tank from the analytic apparatus while solid fine particles are returned thereto from the ultrafiltration apparatus. CONSTITUTION:A plating bath having solid fine particles mixed therein accommodated in a plating bath tank 1 is separated into the plating bath containing solid fine particles and a filtrate in an ultrafiltration apparatus 6. Only the latter is recirculated and supplied to a component analytic apparatus 7 in a preset flow amount while the former is directly returned to the tank 1. The apparatus 7 measures, for example, Ni concn. and a pH and outputs a control signal for holding the measured values to predetermined values. Therefor, when the componential concn. of the filtrate supplied to the apparatus 7 through the apparatus 6 is changed with the deterioration of the plating bath, a control signal corresponding to this change is outputted to a replenishing apparatus 27 and a replenishing liquid is sent into the tank 1 from a replenishing liquid stock tank 6 in an amount necessary and proper in regenerating the plating bath.

Filed: 1988-03-28
Abstract: PURPOSE:To attain small size, light weight, to improve the accuracy of mirror surface and to simplify the mirror surface adjustment by providing a polygonal expansion truss to be freely folded and expanded, an expansion truss with a couple of cable trusses connected by a tensile cable and a reflection mirror surface formed by the combination of plural mesh members of nearly triangle shape so as to form the antenna. CONSTITUTION:A controller selectively applies drive control of an actuator of each expanded truss 11 to apply expansion/contract control to an expanding member 10d thereby expanding or holding the antenna. The mesh member constituting the expansion truss 20 and the reflection mirror surface is expanded or folded. Moreover, if the shape of parabola is changed due to a cause such as an alignment error or thermal distortion in a universe environment, the shape is adjusted into a desired parabolic shape by using the controller again. Since the mirror surface accuracy is set by both the expansion trusses 10 and 20, the highly accurate mirror surface accuracy is ensured. Furthermore, since many hard points exist, the mirror surface adjustment is facilitated.

Abstract: PURPOSE:To hold a constant gas mixing ratio, by mounting a mixing value, a pressure regulator and a signal pressure generation apparatus for generating signal pressure corresponding to the gas pressure of the flowline in the emitting side of said mixing value. CONSTITUTION:In a gas mixer consisting of a mixing value 1, a pressure regulator 2 and a signal pressure generation apparatus 3, the mixing ratio of the gas from a first inflow valve port 11 and the gas from a second inflow valve port 12 is determined by the position of the valve body 13 in a valve box 10. Therefore, by adjusting the position of the valve body 13 by rotating a knob 19, the gas mixing ratio can be adjusted easily. When the emitting flow amount of an emitting flowline 20 is increased, the gas pressure of the emitting flowline 20 is lowered immediately after the increase in the flow amount. The lowering in gas pressure is transmitted to the emitting pressure chamber 51 of the signal pressure generation appratus 3. A pressure regulating spring 54 is operated corresponding to the lowering in the gas pressure of the emitting pressure chamber 51 and the gas inflow amount from a signal gas chamber 62 to a signal pressure generation chamber 58 increases.
